IMPROVEMENT IN HEEL-IBURVNISHING MACHINES.

Specification forming part of Letters PatentNo. 222,409, dated December 9, 1879; application filed i October 20, 1879.

To all whom itmay concern: 5

Be it known that I, THOMAS L. KEIF, of

. Lynn, of the county of Essex and State of Massachusetts, haveinvented' a new and useful Improvement in Machines for Burnishing the Heels of Boots or Shoes; and I do hereby declare the same to be described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a top view, and Fig. 2 a front elevation, of a machinecontaining my invention. Fig. 3 is a "longitudinal section of its burnisher and the arbor thereof. Fig. 4 is a longitudinal section, and Fig. 5 a transverse section, of the jack for supporting the last and shoe. Fig. 6 is a side view, Fig. 7 an edge Q view, and Fig. 8 a transverse section, of the tool for burnishing ogee-shaped, or what are i usually termed French, heels.

The object of my invention is to enable the burnishing of a heel to be expeditiously and thoroughly effected, the burnishing-tool having imparted to it rapid reciprocating rotary movements.

In such drawings, A denotes the burnishing- 1 tool as adapted to slide on and lengthwise of an arbor, B, and against a helical spring,a, The spring serves fixed on the arbor and provided with a pro- M jection, c, to enter a corresponding recess,d,

in the tool, in order when therein to hold the 1 tool from revolving on and independently of I the arbor, and to admit of the tool being rep volved a half a turn on the arbor after the tool may have been moved, so as to disen- L gage it from the projection. The clutch and i i spring enable the tool to be turned a semii revolution on the arbor and locked or clutched,

, so as to admit'of either the front-or rear half of the periphery of the toolbeing brought'into use against a heel, d, of a shoe, 0.

The arbor is supported 1n boxes 0 e, sustained by a standard, D, and such arbor at its outer end is provided with a crank, f, which,

i by a rod, 9, is connected with another crank or eccentric, h, fixed on another arbor, 6.

An endless belt, 70, going around a pulley, l,

the burnishing-tool arbor has imparted to it quick reciprocating rotary motions.

A shoe whose heel is to be burnished issupported by its heel being borne against afrotary heel-rest, 0, pivoted to a jack, E. If necessary such heel-rest may be provided with spurs or points to enter the heel.

A center, 1), hinged to an adjusting screw, 91, arranged as shown in the jack, serves by pressure against the last within the shoe to hold the said last in place and admit of it being revolved, in order to revolve theshoeheel against the burnishing-tool when the latter may be in revolution.

The jack,-by means of a ball-and-socket joint, 1

r, is connected with an arm, 8, extendingfrom the standard. There is pivoted to the cup of the balland socket joint a locking-lever, if,

provided with a spring, u, to force itslower arm outwardly. This lever extends into the cup and also into a recess in the ballwhen the jack is drawn backward. The said lever, while .in engagement with the ball, answers to prevent the shoe-heel or the jack from being drawn up against the burnisher by the helical springs 12 1), extending fromthe prongs of the I jack to a stationary arm, w, projecting from the standard. These springs are to keep the shoe-heel in contact with the burnishing-tool while both are in movement, the springs and the ball-and-socket joint admitting of the jack being freely turned or moved so as to'properly carry the heel in contact with the bnrnish- 5 ing-tool, while the heel with the shoe may-be moved around in the jack.

When ogee -shaped or French heels are to beburnished the burnishing-tool has to be formed as shown in Figs. 6, 7, and 8, the half i as being to fit to and used for the upper or convex portion of the heel, and the half 31 for the concave part of such heel. A section of such a heel is shown in Fig. 9, Fig. 10 being a section of a cavetto shaped heel to which the burnisher represented in Figs. 1 and 2 is adapted to be used.

To estop the movement of the burnishingtool away from its clutch a stationary wire or rod, 2, arranged and projected from the stand PATENT OFF CE ard, as shown, is used, the tool when unclutched resting against the outer end of the wire. The said wire enters an annular groove, a, made in and around the tool, and serves to clear the tool of any dust or particles of leather that might, by gathering on it, obstruct its sliding movement on the arbor or be otherwise injurious.

VVhat I claim as my invention is as follows:

1. In a heel-burnishing machine, the burnisher movable lengthwise on and revoluble upon its arbor, and the latter provided with mechanism-win, the cranks f h, rod g, and arbor i--tbri1nparting to it reciprocating rotary motions, and also with a clutch, b, and spring 0!, arranged and to operate with the burnisher as set forth.

2. The jack supported by a ball-andsocket joint, and provided with two or other proper number of springs, 12, to draw it (the said jack) forward toward the burnisher.

3. The jack supported by a ball-and-socket joint, and provided with two or other proper number of springs, v, to draw it (the said jack) forward, and also with means or devices for locking it (the said jack) back against the draft of the spring or springs, as occasion may require.

4. The burnisher having one half or part, a, of its periphery formed to fit to and hurnish the convex portion, and the other half part or remainder, y, formed to fit to and burnish the concave portion of air'ogee heel, as set forth, such burnisher being for use with an arbor provided with mechanism for imparting to it reciprocating rotary motions, as explained.

5. The burnisher provided with the annular groove a, in combination with the rod z, applied to the standard, and extending into such groove and to operate therewith, substantially as explained.
